A. MERTES TUFT DEFLECTING DEVICE FOR BRUSH MACHINES Filed Nov. 10, 1925 1 M/y/m & 1/ 42 Patented Mar. 6, 1928 UNITED STATES AUGUST MERTES, OF LAKEWOOD, OHIO.

TUFT-DEFLECTING DEVICE FOR BRUSH CMACHINES.

Application filed November 10, 1923. Serial No. 673,982.

The invention has reference to automatically acting machines for inserting bristle tufts in the openings made to receive them in brush backs,'and particularly refers to theconstruction of brushes having unusually long tufts of'projecting wires.

In this machine the tufts of wires are driven simultaneously into rows of closely adjacent openings by means of a reciprocating plunger, and the specific object of this invention is to provide means for holding back or pushing aside the long projecting ends of the tufts ofwire already placed in adjoining openings, which spread apart at 5 their upper ends and would otherwise interfere with the movements of the plunger.

The invention comprises a vibrating arm, having a horizontal member which is interposed between the plunger and the wires'in the last inserted row of wire tufts, and which moves laterally to remove the overhanging wires from the path of the plunger. It also includes automatically acting means for operating the same in conjunction with the movements of the plunger so the parts will not interfere with each others movements.

The device is applicable to a machine such 7 as has been previously described in my applizio cation filed Aug. 21, 1922, Serial Number 583,251, for machine in which tufts of looped wires are driven by meansof a reciprocating plunger successively into spaced rows of openings in a brush back.

The invention is hereinafter more fully described, illustrated in the accompanying drawings and specifically pointed out in the claim.

In the accompanying drawings Fig. 1 is a side elevation of the device. Figure 2 is an end elevation of the device. Figure 3' is a perspective of the bearing block in which the oscillating arm is movable. In these views 1 represents the plunger; 2 is the drive shaft therefor similar to the shaft 2 in the afore- 4- mentioned application; 3 is the bed plate of the machine. At 4 is shown a counter shaft driven by sprocket wheels 5 and 6 and a chain"? from the drive shaft.

Bevel gears 8 and 9 operatively connect the shaft 4 with the transverse shaft 10, having an eccentric pin 11 projecting from the outer end thereof. The pin 11 engages one end of an arm 12 which is slidable in a block 13, which is pivoted at 14; in a support 14 on the frame.

At the outer end of this arm a horizontal rod or bar 15 is moved horizontally by the action of the arm to engage the entire row 16 of wire tufts previously placed in position and. to move their free extremities back from the approaching plunger so as not to interfere with its action or to be themselves bent and distorted thereby. j

The arm is shown in Figure 1- in the act of moving back the Wire tips, and in dotted lines the arm is shown before acting to engage the wires. The armpasses underneath the plunger when the plunger is elevated above the brushes, and its movements are timed so that the arm and plunger will not comeinto conflict with each other.

Having described the invention what I claim as new and desire to secure by Letters Patent is :v

In a tuft deflecting device for a tuft setting brush machine, the combination of a pivotally mounted block, an arm longitudinally movable in said block, a crank timed with the tuft setting mechanism of said machine and opcratively connected with one end of said arm, and a tuft deflecting member at the other end of said arm.

' In testimony whereof, I hereunto set my I hand this 22nd day of October, 1923.

AUGUST MERTES.
